Michael Getler values viewers' submissions, and he and his assistant try to read all letters. The ombudsman's column will address significant issues related to how PBS upholds its own standards of editorial integrity. The ombudsman's role does not replace the long-standing ability for viewers to write or call producing stations or PBS about substantial journalistic issues. Please also refer comments unrelated to the journalistic integrity of PBS content to local stations, producers or PBS. All letters must be signed and are subject to editing.
